Wikipedia is now plpacing rel=”nofollow” on links to external sites. It’s interesting to see that the impetus for this change is from a recently announced SEO contest, where the top winner who can optimize for the phrase “globalwarming awareness2007″ wins a car.

I like this move. In fact, I thought this move is long overdue. But, it’s better late than never. Even though not all spiders observe the rel=”nofollow” directive, the important ones do, and that should be enough to limit spam in Wikipedia.
